A novel copper-catalyzed chemoselective oxidative O-aroylation of 2-acetylphenols, alkyl salicylates and 1,3-dicarbonyl compounds with a wide range of styrene derivatives are described. This approach provides an efficient chemoselective preparation of phenol, alkyl salicylate and enol esters in good to excellent yields. This method represents an alternative protocol for the classical esterification reactions.

Chagas disease, also known as American trypanosomiasis, is classified as a neglected disease by the World Health Organization. For clinical treatment, only two drugs have been on the market, Benznidazole and Nifurtimox, both of which are recommended for use in the acute phase but present low cure rates in the chronic phase. Furthermore, strong side effects may result in discontinuation of this treatment. Faced with this situation, we report the synthesis and trypanocidal activity of 3-benzoyl-flavanones. Novel 3-benzoyl-flavanone derivatives were prepared in satisfactory yields in the 3-step synthetic procedure. According to recommended guidelines, the whole cell-based screening methodology was utilized that allowed for the simultaneous use of both parasite forms responsible for human infection. The majority of the tested compounds displayed promising anti-Trypanosoma cruzi activity and the most potent flavanone bearing a nitrofuran moiety was more potent than the reference drug, Benznidazole.

Polyfunctional compounds comprise a novel class of therapeutic agents for the treatment of multi-factorial diseases. A series of 2-Phenyl-4H-chromen-4-one and its derivatives (5a–n) were designed, synthesized, and evaluated for their poly-functionality against acetylcholinestrase (AChE) and advanced glycation end products (AGEs) formation inhibitors against Alzheimer’s disease (AD). The screening results showed that most of them exhibited a significant ability to inhibit AChE AGEs formation with additional radical scavenging activity. Especially, 5m, 5b, and 5j displayed the greatest ability to inhibit AChE (IC50 = 8.0, 8.2, and 11.8 nM, respectively) and AGEs formation (IC50 = 55, 79, and 54 μM, respectively) with good antioxidant activity. Molecular docking studies explored the detailed interaction pattern with active, peripheral, and mid-gorge sites of AChE. These compounds, exhibiting such multiple pharmacological activities, can be further taken a lead for the development of potent drugs for the treatment of Alzheimer’s disease.
